Even after purchasing a premium-quality oxygen lance pipe, we may face challenges in achieving efficient blowing, heating, or cutting performance. What can bridge the gap between expectations and reality? The key lies in the often-overlooked accessories that are essential for oxygen lance pipe operations.

In this article, we delve into four indispensable accessories—lance holders, sockets, couplings, and press die sets—that play a vital role in enhancing the performance and safety of oxygen lance pipes. By understanding their functions and characteristics, you can optimize your operational efficiency while maintaining safety standards.

The Essential Accessories for Oxygen Lance Pipes

1. Lance Holder

Function

The lance holder connects an oxygen lance pipe to the oxygen supply hose. One end of the holder attaches to the lance pipe, while the other connects to the oxygen hose. Equipped with a valve for opening and closing the oxygen flow, the holder ensures stability, safety, and precision in operations.

Notably, lance holders are designed with an anti-backfire valve that allows oxygen to flow in one direction only, significantly enhancing operator safety.

Characteristics

  • Provides flexible adjustment for positioning and angling the lance pipe.
  • Constructed from heat-resistant and durable materials for enhanced safety.
  • Includes an anti-backfire valve to prevent reverse flow and backfire accidents.
  • Ensures secure connections to minimize oxygen leakage.
  • Features a lightweight design with smooth operation for easy handling.

Categories

Lance holders are available in various sizes based on the diameter of the pipe. It is crucial to match the holder size with the pipe and hose diameters for a secure and efficient connection.

2. Steel Socket

Function

Steel sockets are threaded fittings used to join two oxygen lance pipes to achieve the desired length for safe operations. They screw onto the threaded ends of the pipes, ensuring a seamless and secure connection.

Characteristics

  • Manufactured to comply with international standards such as BS, ASTM, and JIS.
  • Suitable for all sizes of threaded oxygen lance pipes.
  • Customizable to meet specific thread standards requested by customers.

Categories

Sockets are classified by size and material:

  • Aluminum Sockets: Ideal for aluminum pipes.
  • Steel Sockets: Suitable for steel pipes.
  • Proper material matching between the socket and the pipe ensures durability and compatibility.

3. Steel Coupling

Function

Couplings are designed for threadless connections and are particularly suitable for oxygen lance pipes without threaded ends. Their primary function is to create an airtight seal, minimizing gas leaks and enhancing safety during operations.

Characteristics

  • Available in various sizes to suit different pipe diameters and applications.
  • Engineered with elasticity compatible with the pipe’s steel grade for durability.
  • High elongation properties (above 40%) ensure optimal performance under stress.

Categories

Couplings are categorized into three main types:

  • Standard Coupling: Requires a press coupling machine for connection.
  • Quick Coupling: Can be manually connected without a press machine. Ideal for pipes with an outer diameter under 21.4mm.
  • Press Quick Coupling: Features one pre-pressed end for time-saving assembly, suitable for confined spaces and threadless pipes.

4. Press Die Set

Function

Press die sets are essential tools for use with press coupling machines. They press couplings into oxygen lance pipes, ensuring a secure and airtight connection. Each press die set is tailored to fit a specific pipe size.

Characteristics

  • Made from durable, wear-resistant materials.
  • Designed for long-lasting use and reliability.
  • Available in various sizes to cater to diverse operational needs.
  • Easy to assemble and replace for smooth operations.

Categories

The inner diameter (ID) of the press die set corresponds to the outer diameter (OD) of the press coupling. Each set comprises two identical parts that work as a pair to ensure a tight fit.

Conclusion

Efficient and safe use of oxygen lance pipes relies heavily on the compatibility and quality of essential accessories like lance holders, sockets, couplings, and press die sets. By understanding their functions, characteristics, and proper usage, one can significantly improve the performance and safety of your operations.
